We will study the effects of intensive rehabilitation in PD on plasticity with a multimodal approach. We will define first, whether exercise in PD restores the potentiation of the motor cortex to normal levels with both 5 Hz-rTMS PAS and beta modulation and whether such improvements are accompanied by structural changes studied with diffusion MRI tractography and network analysis (Aim 1). With the study of muscle synergies and spatiotemporal organization of the spinal motoneuronal output during gait and reaching movements we will define the presence of functional changes in spinal cord mechanisms and connectivity and whether such changes are global or involve selective districts (Aim 2). Finally, we will study post-exercise changes in sleep pattern, as sleep is impaired in PD and plays a crucial role in the definition of plasticity-related phenomena (Aim 3). This project will generate breakthrough data on the mechanisms of exercise, novel biomarkers to monitor efficacy of treatments and thus, possibly leading to better restorative, disease-modifying and symptomatic therapies for PD.
Parkinson's disease (PD) is a neurodegenerative disease characterized mainly by motor symptoms, in particular rigidity, akinesia, tremor, which are associated with postural reflex deficits, impaired balance and gait deficit, with consequent significant limitation and impairment not only of functional independence but also of social and community life. Postural instability leads to the appearance of accidental falls due: to the sudden loss of balance which is associated with the impossibility of implementing the right compensatory parachute reflexes; This can lead to serious consequences in these patients, in particular musculoskeletal trauma. In addition, progressive alterations of the gait lead to the phenomenon of freezing or freezing (FOG), in itself the cause of frequent falls. Physiotherapy in PD, including cueing techniques, treadmill training, and cognitive movement strategies, has been shown to improve balance and gait in PD patients. When we talk about subjects affected by PD. Often the painful symptomatology is an obstacle to intensive rehabilitation treatment. The study conducted by José Fidel Baizabal-Carvallo (10-2020) showed that a training program that includes relatively low workloads provided benefits in different aspects of the Freezing of Gait and greater mobility, with a lower incidence of falls and consequently of musculo-articular damaging events. The Alter-G M320 anti-gravity treadmill allows a lifting force to be applied evenly and comfortably to the patient's body. Lightening the body up to 80% of the weight, thanks to the pressure variation inside the air envelope, Alter-G allows patients or athletes to walk and run respecting motor patterns without compromising the biomechanics of eccentric movement. Through precise air pressure control (DAP - Differential Air Pressure) allows to improve aerobic conditioning activities without increasing the risk of stress injury. In addition, compared to traditional rehabilitation in the pool, AlterG allows maximum precision in the alleviation of discharge, being able to vary the load by one percentage point at a time.
Parkinson's disease (PD) is one of the most common neurodegenerative diseases characterized by the progressive loss of dopaminergic (DA) neurons in the substantia nigra compacta (SNc) and aggregation of Lewy bodies in neurons. Although aging, oxidative damage and neuroinflammation have been recognized to play crucial roles in the pathogenesis of PD, the precise etiology remains obscure. Emerging evidence suggests PD is a systemic metabolic disease, and metabolic abnormality correlates with functional alternations in PD
This research is being done to develop a unique matching process for caregivers of persons living with dementia, such as Alzheimer's disease, Lewy body dementia, frontotemporal degeneration, or other dementia syndromes. Dementia caregivers often assume greater caregiving burden than do non-dementia caregivers, and the caregiving duration tends to be longer. Many caregivers do not have the adequate support they need. Peer-to-peer support has been shown to improve quality of life, more engagement with services, improve caregiver health, and reduce hospitalizations in the person they are caring for. This study will help determine whether caregivers of persons with dementia would find a technology-based caregiver matching program valuable for the purpose of emotional support.
Parkinson's disease (PD) is a debilitating neurodegenerative disorder occurring in 7 million patients worldwide. PD is caused by progressive loss of nigro-striatal dopamine cells, which causes motor symptoms such as slowness of movement and tremor, and non-motor symptoms such as cognitive dysfunction. Converging clinical evidence indicates that PD patients are very sensitive to the effects of psychological stress. There is a high prevalence of stressrelated neuropsychiatric symptoms in PD: 30-40% of patients experience depression and 25-30% have anxiety. Furthermore, stress worsens many motor symptoms, e.g. tremor, freezing of gait, and dyskinesia. In addition to these immediate negative effects, chronic stress may also have detrimental long-term consequences, and specifically by accelerating disease progression, as suggested by animal models. However, this hypothesis remains to be confirmed in humans. Better evidence about the impact of stress on PD would have major treatment consequences: novel stress-reducing interventions may have symptomatic effects, and perhaps also disease-modifying effects. The aim of this study is to test whether a stress-reducing intervention improves clinical symptoms, slows neurodegeneration, and/or enhances neuroplasticity in PD. In a randomized controlled trial, the investigators will compare a stress-reducing mindfulness-based intervention group (MBI; one year) to a treatment as usual (TAU) group on clinical symptoms, cerebral markers of nigro-striatal dysfunction and stressor-reactivity (MRI), and inflammatory markers (serum).
It is unclear why humans typically swing their arms during gait. To date, the debate on how to arm swing comes about (i.e. whether it is caused by accelerations of the shoulder girdle or muscular activity) is still going on. There needs to be consensus on whether the arm swing is actively controlled or merely passive and on why humans swing their arms during walking (i.e. what the purpose of arm swing is, if any). Suggested reasons include minimising energy consumption, optimising stability, and optimising neural control. Pathologies such as hemiplegia after stroke, Parkinson's disease, Cerebral Palsy, Spinal Cord Injury, and Multiple Sclerosis may directly affect arm swing during gait. Emerging evidence indicates that including arm movements in gait rehabilitation may be beneficial in restoring interlimb coordination and decreasing energy expenditure. This project hypothesises that the arms swing, at least at low and intermediate walking speeds, reflects the body's Center of Mass (CoM) accelerations. Arm swing may thus depend mainly upon the system's intrinsic mechanical properties (e.g., gravity and inertia). In this perspective, the CoM is seen as moving relative to the upper limbs rather than the other way around. The contribution of major lower limb joints, in terms of power injected into the body motion, will be simultaneously explored. The study aims to investigate the mechanism and functions of arm swinging during walking on a force treadmill. To simulate asymmetric walking, healthy subjects will be asked to walk with a toes-up orthosis to induce claudication and asymmetry in ankle power. In this way, it will be possible to highlight the correlation among arm swinging, ankle power, and the acceleration of the CoM in a 3D framework. In addition, subjects affected by unilateral motor impairments will be asked to walk on the force treadmill to test the experimental model and highlight significant differences in the kinematic parameters of the upper limbs. The question of whether arm swing is actively controlled or merely passive and the relationship between arm swinging and the total mechanical energy of the CoM will be faced. Asymmetric oscillations of the upper limb will be related to dynamic asymmetries of the COM motion, and of the motion of lower limbs. In addition, cause-effect relationships will be hypothesized. Finally, the dynamic correlates of upper limb oscillations will make the clinical observation an interpretable clinical sign applicable to rehabilitation medicine. Results from the present study will also foster the identification of practical rehabilitation exercises on gait asymmetries in many human nervous diseases.
The purpose of the study is to determine if using SIS System for DBS planning results in less distance between the planned target location and the actual implanted lead location than DBS planning without SIS System.
Although TeleRehabilitation (TR) is widely accepted as an appropriate model for the provision of professional health services in the field of physiotherapy, with already established standards, guidelines and policies, there are still few studies in the literature on the use of TR as a rehabilitation tool in people with Parkinson's Disease (PD). Therefore, further studies on the efficacy of TR in the management of motor and non-motor symptoms of PD are needed. The study TEMPO aims at assessing the efficacy (in terms of autonomy in carrying out the activities of daily life) of a home TR program based on serious games in people with PD compared to conventional day-hospital treatment.
The purpose of this study is to evaluate the feasibility and effectiveness of a non-contact Rock Steady Boxing class delivered to participants with Parkinson's Disease via an in-person community-based program. The study will also assess the overall feasibility of integrating an in-person community program within a neuromuscular course in a Doctor of Physical Therapy program. Specific Aim: To examine the effects of an in-person community-based Rock Steady Boxing class on the functional mobility, functional endurance, cardiovascular capacity, visual-motor reaction times, quality of life, mood/affect and overall physical activity completion and fear of falling on individuals with Parkinson's Disease.
